我想问有没有简单的输出方法呢？我这样写的感角不用每次都有一条输出语句，这样会不会太繁琐。

Question

public class HelloWorld{       public static void main(String[] args) {        int one = 10 ;        int two = 20 ;        int three;         three = one+two;        System.out.println("three"+"="+three);         three += one;        System.out.println("three"+"="+three);         three -=one;        System.out.println("three"+"="+three);         three *= one;        System.out.println("three"+"="+three);         three /=one;        System.out.println("three"+"="+three);         three %= one;        System.out.println("three"+"="+three  );                         }}

Answer 1

定义一个静态方法output，参数类型为int，方法体中是输出语句，输出语句参数即output方法的参数。这样就只用写一次System.out.print方法，需要输出时调用output()方法即可
